If the built in Lithium batteries are non-removable, what happens when they stop re charging.?Is it then useless?

Apparently so, but I'm not really not sure. I couldn't find any product like this that has replaceable, rechargeable batteries. If someone knows of some, let me know. (I know there are a few that use regular batteries.)

The description states it has lithium technology which will last many many months if it is fully charged and not being used. I'm very happy with mine and it has plenty of power to recharge phones and tablets without having to recharge the unit itself. I hope this helps.

I had issues with that. And the battery. Bad cell. Return was quick and painless tho. Amazon got me a new battery in 2 days. The charger I would recommend only using one that specifies lithium. Battery tender was out of stock so I got a battery tender plus charger. You can leave it on the battery for long periods and it's safe with lithium. I hope this helped.

You can leave it on charge for as long as you want if the charger is not malfunctioning - the batteries stop charging once the light turns green. Lithium batteries last the longest when they are kept charged. YOu don't need to cycle the batteries through charge discharge cycles - if anything - this is more harmful to the life of the battery. The charger will cut off and the light turns green once the batteries are fully charged. IF it didn't, the batteries have the potential to explode or catch fire.

I recharge mine every night. Lithium-ion batteries do not need a full discharge and recharge to maintain its battery life. Whether you discharge it 25%, 50% or 75% before charging it doesn't effect the life of the battery. I've had this battery for a year of constant use and it still works awesome.Overcharging or discharging too low is bad for the battery but most phones stop charging or shutoff before this is an issue.

I don't believe it will hurt the batteries, but in general with Li-ion batteries it is a good idea to remove them after they are charged. They will hold their charge for months after being re-charged, so why would you want them left in the charger? It is always safer to remove the batteries and unplug the charger.

I wouldn't think it does. Lithium ion batteries are better at handling overcharging but the speaker displays a faint red light when fully charged and I believe it shuts it off form charging. Honestly, the battery life is go great, keeping the charging cord stored or using the charger for you phone (which is the exact same as non-Apple mobile phones), you wouldn't need to keep it plugged in all the time.

I would strongly recommend against attempting to use a disposable lithium battery in this charger. There is a high risk of the disposable battery damaging the charger.

yea it will be fine to leave it plugged in and the batteries in. they are lithium ion type batteries the same kind in laptops and cell phones. so they will charge up then the charger will just keep them charged till your ready to use them, i dont know about long term though like over a week or two probably wouldnt be great for them.

It depends on the battery type. Ni-Cd batteries will develop "memory" so if you leave it on the charger all the time between small uses and not full uses, it will eventually ruin your battery. NiMH and Li-Ion batteries don't suffer from this effect. http://www.all-battery.com/batterytechnicals.aspxhttp://www.ebay.com/gds/What-is-the-difference-between-NiCad-NiMH-and-Lithium-/10000000002033731/g.html

You can charge the batteries whenever you choose. I usually do it when the camera shows 1 bar (out of 3). I don't think there is a loss of capacity from recharging a non-drained battery, but I don't know. I have used these batteries for about a year, taken more than a thousand pictures, and have not noticed any loss of battery charge duration. But this is anecdotal - not something I have tested for.

I have used mine a lot and just recharge it the charger. You can buy 3.6 v Lithium-ion batteries so if your batteries are not recharging I would open it to see which battery you need.

you cant shut it off, but all the times I have used mine, the battery depletes fairly evenly, never had one or more cells totally deplete while the others had a decent charge. I have only used it on 3 cell and 4 cell batteries. works great. are you using a balance charger for your batteries? that's all I can think of why your battery depletes so unusual. if not, get one that will also discharge your batteries properly for long term storage. you cant store them fully charged or drained.

The lithium battery will hold a charge for up to 18months when not in use. No memory effect so charge away!

It specifies Lithium rechargeable batteries. I am having trouble finding rechargeable batteries that are lithium...most are Ni-MH. Can these still be used? (Sorry for the ignorance...I have never used rechargeable batteries!)

I'm sure they have a lithium ion battery since other batteries can't provide that kind of power. It is not recommended to deplete lithium batteries since they have no memory and you can simply keep it charged up on the charger without fear of it losing performance after each cycle. One thing to avoid is high temperatures which will shorten the life of the battery. Most lithium batteries last 3-5 years. Hope that helped. Regards, RAM

Right. This one isn't rechargeable, it needs to stay plugged in. They do have other models that are rechargeable, I believe. They are usually a bit more expensive. But keep in mind that those batteries will slowly die over time.
